I remember pre sanding sample mounts by hand and drawing blood not realizing it. Auto polisher is what ya need , look up struers polishing machine. Polishing samples for inspection in SEM you typically go down to 3 um at least then if you are taking photos for a report I’d do 1um then maybe a 300nm and a special polish that’s chemical reaction more than a a grit. You can get locally flat to a few 10s of nm. That flat you shouldn’t need any sort of paste if you make sure to keep the surface clean.
Been doing this with an upside down hand sander. Works pretty good so far. Did 2 2700x and 1 8083. Idk about total differences on any but my personal rig and seems to have taken my 12 degree Delta down to 4 ish.
I know it's just a joke... But I have to reply, just in case anyone is actually stupid enough to take it seriously (Particularly since it's a top comment)... Potters wheels while they look similar are not the same as metallographic polishers, they have far lower tolerances, and of course any method of attaching sandpaper to them would have to be DIY... When polishing a IHS or CPU Die there's a reason you do it on glass or a mirror when doing so manually, and it's because both glass and mirrors in order to show no optical distortion have to have high tolerances, that is extremely relatively flat. Potter wheels don't have this requirement, and so you will not get an even grind out of one if you DIY it, and are likely to damage your CPU. The reason metallographic polishers are so expensive is they have the same tolerances as a Whitworth Surface Plate, or just a Surface Plate I guess, although I like giving credit where credit is due. The point is, what seems to be 'roughly' the same design, is actually a massive difference in engineering precision, and you need that precision when screwing around with trying to make a 'perfectly flat surface.' Again, the original poster was no doubt just joking, this isn't a reply to him, just a comment for anyone who didn't get the joke to spare them some agony..
@@dragoonsunite oh god I hope no one is that stupid... But from conversations I've had on other video threads it wouldn't surprise me. The tolerances would have to be the same as a surface plate (go watch "This old Tony" or "Abom79" they use them to check tolerances pretty frequently anyone who has never seen one used). But the bearings that allow the plate to turn would be precision too similar to a lathes bearings which are very expensive £400 each for the one I'm rebuilding. So yes it was a joke, if you want to do anything like this at home use a mirror or buy a surface plate and do it by hand. (I am however now slightly interested how close to flat you could get one of these in a lathe with the right setup... I wonder if Tony would do my 7700k for me as I don't care about it). And anyone else thinking it, I was surprised they didn't use a surface grinder too, seems like that was made for this job...
Andrew Culverhouse A simple 12” polished stone tile or piece of glass from Hone Depot (both very flat), some wet dry sandpaper and elbow grease will work too.
I am a lab manager for a petrographic thin section lab which requires a lot of lapidary knowledge. The rounding you see on the outside is from the rotation of the cpu on the grinding surface. Two things you can do to improve the planeness of the cpu is to 1. hold it as low as possible to limit rotational forces and 2. don't hold the cpu in one spot on the grinding surface. What I saw in the video will guarantee an uneven grind just the mechanical fact that the outside of the grinding disc spins faster than the center. The most advisable motion to perform is a figure 8 motion. This will prevent you from grinding too long in one spot and also wear the grit paper down evenly.
I can't say I've ever lapped a cpu or heasink but I do lapping and polishing in machining, I'd say if you want to do this at home get some glass or a mirror big enough to lay a full sheet of wet&dry paper get the paper soaking wet then lay it on your glass and the water should keep it in place for what you're doing...if it moves around a lot you're likely using way too much pressure, just go in a nice wide figure 8 barely pressing on it at all. It should take a long time so pick a weekend or a day where you don't have to do anything else and for the love of god take your time, work up the grits with pleanty of water you can't really use too much water and don't get impatient or skip grits.
i worked with a similar disk sanding machine with higher Grit size you dont even notice that your fingers are touching until you see the blood flowing. Steve had the advantage to sand a CPU i had to sand verry small precious metal samples. my thumb was bigger as some samples.
the prophecy was true... Tech Jesus spilled his blood in redemption for manufacturer's sins again. I feel blessed. May your framerates be high and your temperatures low, fellow enthusiasts!

This was cool, but we want the behind the scenes footage. The one that has y'all sitting around a campfire sipping wine discussing hair care techniques.
Oh gosh I thought u were gonna say the edition where kingpin boofooed Steven while they're pulling each other pony tails cuz I would sooooo not fuckin buy that

Steve's done his first real lapping, He did it at Vince and Tin, Sanded it until his fingers bled, Was the winter of '19 (On the tune of Summer of '69)
I just use a rubber sponge pad to hold the CPU down, makes it much easier to eventually apply pressure and don't have to worry about sanding through your skin lol. Also, when wet sanding 3M sand paper wears out quick and quickly turns 200 grit into crappy 400-600 grit. I found Gator sandpaper takes much MUCH longer to wear and works much faster.
@Brad Viviviyal it may be Italian dialect but where my parents come from near Naples "shine" is "lucido" e.g., let's say in Englisg "it is shiny" is said "è lucido" in our dialect. In modern Italian however it is "è brillante".
Die lapping and heatspreader lapping was a huge thing back when Pentium IV was released. People came up with all kinds of rigs, but the best results can be achieved by using the same tools and following the same rules that people use for knife sharpening. What you need are high quality grinding stones, a stone holder, a diamond stone flattener and the skills to rock the CPU back and forth without wiggling it.
you could make sandpaperdisc and holder gyrostabilized for ensuring perfect flatness. another option would be a self stabilising device, whith laser - measures distance to 4 points of sandpaperdisc and 4 points to the cpu.
So i just did this by hand thinking it was an easy way to lose a couple of degrees. Used a pane of glass to ensure I had a flat surface and went from 80 grit to 120 grit to 200 grit etc all the way to 2000 grit and achieved a mirror like copper finish. Only thing is it took me 5 hours! I did this on a Xeon X5675 that i bought off Ebay. The heat spreader is soldered so no delid. This heat spreader had 2 giant dents which I saw when sanding. I spent most of my time sanding with lower grits and finally achieved a flat surface. If I had to do it again I would buy 45 grit to speed things up. Once you have a flat surface you spend 5 min at each grit to get mirror finish. Also lapped air cooler (Corsair A70) worried about blasting though a heatpipe . Took less than 30 min to level the cooler. Conclusion : Do it, few degrees here few degrees there really add up. Oc'ed the X5675 to 4.35ghz for AZ summer, winter run daily 4.5ghz. Temp usually in 70s when stress testing. I imagine I saved 3-6 degrees total.
@@Ruhrpottpatriot the answer is ~-30c improvement. Tested with a 5960x and lapping the ek block also....... im not a professional i did it on my glass table. So ye thats totally necessary if you spend so much for a cpu with custom cooling and you see full load 80c on 1.228vcore at 4.4ghz
@@ChrisGR93_TxS See, but you're already part of that "1%". A normal user will buy that CPU, insert it (if even; most buy pre-built systems), change nothing in the BIOS and use it. Those settings let the CPU run, even with turbo well within specs. No need to spend money to make it flatter
@@AndreiNeacsu You missed the point. It doesn't matter which CPU it is. No company can afford to make IHS' that precise that the 1% who need them that precise needn't lap them. For the average user the current IHS flatness is good enough.
I have never ever seen this process before! Recently, my eight year old motherboard failed. I had an Intel i7-CPU that I saw was looking oval? Putting a steel ruler across it, it was clearly bulged high at the center. Not good for matching with a cooler! I took engine lapping compound and manual circular motions with constant repetitive turning at 45 degree turns to keep a flat surface. I saw an even and flat reduction until completely flat! You do not need to remove all of the Nickle coating! As long as you remove all the high spots and have a 4 point (all corners) contact showing a clean clear flat surface, that is then a flat surface! Check it at all points >>>> across midpoints between each corner and then at corner to corner with the steel ruler. No light seen under the ruler? Then it's flat and ready to mate with the cooler!!!! Patience and common sense. No need for this fancy machine! Cheers
I love how Kingpin is so detached to the price of components and TiN is "it's $10 cheaper" pretty funny especially when Steve is going all robber status sanding off his fingerprints. . .
So... what if you buy a copper IHS... sand it so it's like a mirror, then use a liquid metal/solder technique for the TIM... I wonder if you could solder it yourself? Would be one hell of a cool running CPU I think.
I've heard to solder the IHS on you need an oxygen free kiln, one which uses argon or nitrogen, otherwise the specific solder used can oxidise, but yeah would be super cool
You can go really far then that, get IHS made of silver, polish it to a mirror, balance height of every edge. But direct die contact (copper tubes directly on CPU die) still be effective since layers between CPU and cooler tubes are eliminated.
I've done lots of metal polishing on lapping machines for material science research. Part of the challenge is applying even pressure. It's very easy to apply slightly more pressure on one side which would lead to an uneven surface. Nonetheless an interesting video! May have to try this at work.
Good work guys. I am working in a metallography lab. I do a lot of grinding on very similar machines. I can appriciate the hard work on the sanding machine.
Man this is cool hangin with the OG's listening to KingPin and Tin along with you Steve. You ended 2018 very well and have a big start on 2019 content. There is a Holy Grail out there and I'm betting on GN to find it.
@@angelodagnolo984 I'm sure you'll see it soon enough. Steve did this for a reason. We're not talking lower temps necessarily, rather lower core-core deltas. You think Vince does this for fun? If you want proof go find it. Again, you think people do this just for the Lols?
Could be cool to see both IHS and cooler lapped to a point where you could ring them together, would still need paste and prob yield no benefits, but hey, you could always use it as a showpiece, floating heatsink sticking to a CPU without glue or screws.
The "Ghost" reference thumbnail should become a T-Shirt motive ! And btw. Smiley CPU draws blood witch form another smiley - you guys do practice dark magic :D
Man I haven't hand lapped CPUs in more than 15 years .... Back in the mid-90's my brother was into restoring and and using antique wookworking tools and he got a hold of the huge 1" thick piece of glass at least 1ft x 2 ft for sharpening draw planes and I talked him into letting me borrow it and away I went lapping CPUs and heatsinks .... then output transistors and heatsinks in high watt power amps for concert sound systems and then doing before and after testing (Yes it does make a difference but probably not enough for the time involved) ..... There is some kind of special thick dye that is used in precision lapping of heads, blocks, intake and exhaust manifolds that you can use to judge how flat it really is down to micro-millimeter resolution. Lapping times were judged by the length of a baseball or football game on the TV in the workshop "How long did that one take you?" " Oh about 8 innings" .... "OK we'll use 220 for the 1st quarter and swap to 400 for the 2nd quarter, take a break for halftime and go to 800 for the 3rd ..."
I think its unacceptable for such a high priced CPU that you have so much temprature problems because of a cheap IHS. Its like you buy a Porsche and the steeringwheel is tilted.
People doing this at home here is how you do it (and I may make a video in the future): Find a glass top table. Place 600 grit sand paper flat on the glass. Spray with water. Make figure 8 pattern with the cpu until it is all copper showing. Switch to 2000 grit sand paper until the 600 scratches are gone. Switch to 3000 grit sandpaper until the 2000 scratches are gone. Good enough! Oh and when you are done, wash it all off with distilled water to flush out any particles. Flush with IsoPropyl Alcohol to mix with the water and help evaporation. Put the CPU in the oven on "warm" setting if you live in a cold climate or just put it outside if you live in a warm one and let it all evaporate before using.
You can leave it in the hole. The hole is only there to vent flux gas from when the heat sink was soldered to the CPU. Plugging it after the soldering has no effect one way or the other.
Leading edges tend to dig in and cut faster so it's best to apply the clamping load 30-40% in from the trailing edge. You can even see it in multi piston brake callipers, by the different diameter pistons.
Far from actually lapping it and far from perfect. Once you get the helium lamp out and an optical flat are you really lapping. This was just using a power sander to "even out" the surface.
One would know by sticking two "lapped" things together. If it has a stickiness to it, then it's pretty darn flat. Wouldn't even need thermal grease at that point.
I never thought I would see a metallographic polisher on Gamers Nexus. I'm glad my super niche skillset could be used in another super niche application.
This is not how lapping a surface is done. Please do not to this, this is incorrect in every way. Where's the optical flat and monochromatic light to verify results?
From experience, I know that the leading edge will remove more material. I sand other material than CPU's, but I alway turn the material 180 degrees to sand as flat as possible. Cool machine!
Had a massive improvement on air back in the late 2000's when I finally decided to lap my q6600 and zalman cooler. Wish I had that machine as I used a mirror and different grit sandpaper

@@ChrisGR93_TxS See, but you're already part of that "1%". A normal user will buy that CPU, insert it (if even; most buy pre-built systems), change nothing in the BIOS and use it. Those settings let the CPU run, even with turbo well within specs. No need to spend money to make it flatter
@@AndreiNeacsu You missed the point. It doesn't matter which CPU it is. No company can afford to make IHS' that precise that the 1% who need them that precise needn't lap them. For the average user the current IHS flatness is good enough.
@@Ruhrpottpatriot Why then just don't offer for 1% DYI Kit? CPU + IHS. Add whatever you want between them, lap CPU die, Lap IHS... But no.
I have never ever seen this process before! Recently, my eight year old motherboard failed. I had an Intel i7-CPU that I saw was looking oval? Putting a steel ruler across it, it was clearly bulged high at the center. Not good for matching with a cooler! I took engine lapping compound and manual circular motions with constant repetitive turning at 45 degree turns to keep a flat surface. I saw an even and flat reduction until completely flat!
You do not need to remove all of the Nickle coating! As long as you remove all the high spots and have a 4 point (all corners) contact showing a clean clear flat surface, that is then a flat surface! Check it at all points >>>> across midpoints between each corner and then at corner to corner with the steel ruler. No light seen under the ruler? Then it's flat and ready to mate with the cooler!!!! Patience and common sense. No need for this fancy machine!
Cheers
I love how Kingpin is so detached to the price of components and TiN is "it's $10 cheaper" pretty funny especially when Steve is going all robber status sanding off his fingerprints. . .
No need to track prices when it's always free
Mostly watch GN for benchmarks and stuff. But had to stop by to give a like and say that thumbnail is absolutely priceless.
So... what if you buy a copper IHS... sand it so it's like a mirror, then use a liquid metal/solder technique for the TIM... I wonder if you could solder it yourself? Would be one hell of a cool running CPU I think.
That would be insane probably. but then in that case why not just delid entirely.
Why not delid and sand silicone? 😋
I've heard to solder the IHS on you need an oxygen free kiln, one which uses argon or nitrogen, otherwise the specific solder used can oxidise, but yeah would be super cool
The silicon needs to be specially treated as does the ihs for the indium based solder to work. Der8auer did a video on soldering your own cpu.
You can go really far then that, get IHS made of silver, polish it to a mirror, balance height of every edge. But direct die contact (copper tubes directly on CPU die) still be effective since layers between CPU and cooler tubes are eliminated.
I've done lots of metal polishing on lapping machines for material science research. Part of the challenge is applying even pressure. It's very easy to apply slightly more pressure on one side which would lead to an uneven surface. Nonetheless an interesting video! May have to try this at work.
Tech Jesus bled for Intel's sins.
DavidGX nice rendition man
Good work guys. I am working in a metallography lab. I do a lot of grinding on very similar machines. I can appriciate the hard work on the sanding machine.
@GN reached a whole now level in thumbnail
Reminds me of DPreview's Chris and...
Glad to see KINGPIN rocking with the G Shock gang!
Wearing a regular watch these days is almost considered going retro.
Love my G Shocks.
Tech Jesus blessed that CPU with his own blood (8:50). It will goeth where none before have.
Man this is cool hangin with the OG's listening to KingPin and Tin along with you Steve. You ended 2018 very well and have a big start on 2019 content. There is a Holy Grail out there and I'm betting on GN to find it.
Jesus Tech & Kingpin bromance for lapping a CPU with hand gestures😂
Man I'd watch Vince and Tim just F around at their shop mon-fri every damn week. Absolute Legends...Tech Jesus ain't no slouch either!
Where the hell are the results?!?!?!?! We want results! Awesome thumbnail btw!
Its a joke...... there is NO way that will make any difference, not one IOTA! of a difference.....
@@angelodagnolo984 Wrong
@@dickr9345 really.... show me the proof!
@@angelodagnolo984 Derbauer did similar things not only with ihs, but with the die itself, there are differences. Just look for it. It doesn't hurt.
@@angelodagnolo984 I'm sure you'll see it soon enough. Steve did this for a reason.
We're not talking lower temps necessarily, rather lower core-core deltas. You think Vince does this for fun?
If you want proof go find it. Again, you think people do this just for the Lols?
you guys really nailed the top/bottom dynamic.
I didn't know the Skylakes came with sandy beaches.
I've been sanding ihs for over a decade. Cool that it's finally a thing.
Could be cool to see both IHS and cooler lapped to a point where you could ring them together, would still need paste and prob yield no benefits, but hey, you could always use it as a showpiece, floating heatsink sticking to a CPU without glue or screws.
I hate lapping by hand, I do not have a machine. However, lapping by hand I have never sanded my skin off! Thank you for this video.
"sandpaper Enthusiast" :D good description
That brings back memories of sanding a Celeron 433 until I could see my reflection. I just had a mirror with sandpaper tape to it though
Did it with a pentium dual core, then finished it with brasso and a piece of leather. Looked great
Vince: I told you he won't know if his fingers are being sanded off
that sound as soon as the IHS touches the grinder sends shivers down my spine
Vince looking like the bad guy king from Shrek
Gamers Nexus tech videos are on a whole different level than other tech channels.
my 2700k 8 years ago was concave by over .025 thousands. i know because i put a depth mic on it and measured it.
Disgraceful quality control.
@Brad Viviviyal no possible way you would know i measured it at work.
I lapped my AMD FX 8350 by hand using 400 - 2500 grit paper and followed up with a high quality thermal paste. Well worth the effort.
The bromance is strong in this one. But I think Steve and Roman is the cuter couple.
The "Ghost" reference thumbnail should become a T-Shirt motive ! And btw. Smiley CPU draws blood witch form another smiley - you guys do practice dark magic :D
Good morning. Wow. Amazing. So cool. Very, very nice. Greetings from Poland.
I want what he's having
Popped up in suggested,now ready for next collab with kingpin..
An MTBer sanding CPU's:
"Skin grows back..."
😄
OMG what a lapping machine! Only worthy for Kingpin and Steve! ;)
You want to experience TRUE LEVEL?
DO YOU?!?
Moans fullfilled by satisfaction**
Man I haven't hand lapped CPUs in more than 15 years .... Back in the mid-90's my brother was into restoring and and using antique wookworking tools and he got a hold of the huge 1" thick piece of glass at least 1ft x 2 ft for sharpening draw planes and I talked him into letting me borrow it and away I went lapping CPUs and heatsinks .... then output transistors and heatsinks in high watt power amps for concert sound systems and then doing before and after testing (Yes it does make a difference but probably not enough for the time involved) ..... There is some kind of special thick dye that is used in precision lapping of heads, blocks, intake and exhaust manifolds that you can use to judge how flat it really is down to micro-millimeter resolution. Lapping times were judged by the length of a baseball or football game on the TV in the workshop "How long did that one take you?" " Oh about 8 innings" .... "OK we'll use 220 for the 1st quarter and swap to 400 for the 2nd quarter, take a break for halftime and go to 800 for the 3rd ..."
How does the cpu ihs get validated for flatness when all is said & done? Granite surface plate & feeler gauge?
sixtyinsix also wondering this
yes, they should definitly use a surface grinder and a good granite place, they aren't even that expensive...
OMG, you two are F*ing hilarious. The look on both of your faces in the Ghost parody shot is worth saving to my desktop.
I think its unacceptable for such a high priced CPU that you have so much temprature problems because of a cheap IHS. Its like you buy a Porsche and the steeringwheel is tilted.
I never knew I could be so interested by watching someone sand something.
Kingpin sort of looks like Count Dracula and TiN's his Igor henchman. I guess that explains blood sacrafice from Steve
People doing this at home here is how you do it (and I may make a video in the future): Find a glass top table. Place 600 grit sand paper flat on the glass. Spray with water. Make figure 8 pattern with the cpu until it is all copper showing. Switch to 2000 grit sand paper until the 600 scratches are gone. Switch to 3000 grit sandpaper until the 2000 scratches are gone. Good enough! Oh and when you are done, wash it all off with distilled water to flush out any particles. Flush with IsoPropyl Alcohol to mix with the water and help evaporation. Put the CPU in the oven on "warm" setting if you live in a cold climate or just put it outside if you live in a warm one and let it all evaporate before using.
Lol, I thought that photo was from that guy and his girlfriend
Kingpin seems like just a real straight up guy. I'll bet he'd be great to work with.
He put the grease in that hole.. how do you get it out again? or is that not necessary?
You can leave it in the hole. The hole is only there to vent flux gas from when the heat sink was soldered to the CPU. Plugging it after the soldering has no effect one way or the other.
Now with that blood drop on the machine ...the machine came to life ....with Steve voice and talkback to everyone in the lab REGARDLESS!;)
A mill would do this in seconds. Just ask at nearest engine repair shop. They can make it super flat for bottle of beer)
Copper is really grabby to mill and would be a nightmare to mill a part this thin, a well set up surface grinder would probably be a better option.
Leading edges tend to dig in and cut faster so it's best to apply the clamping load 30-40% in from the trailing edge. You can even see it in multi piston brake callipers, by the different diameter pistons.
That's lame of intel, they cheaped on the cheapest part of a $2,000 CPU
Young padawan Tech Jesus learning from the master ;) Always a pleasure to see Vince.
Lol that thumbnail btw first?
LOL. It's a reference from the movie Ghost with Patrick Swayze and Demi Moore.
naughty lapping
@@jayireland561 yeah a I know. The one with whoopy Goldberg also.
God that grinding sound. For some reason it made my toes curl.
Far from actually lapping it and far from perfect. Once you get the helium lamp out and an optical flat are you really lapping. This was just using a power sander to "even out" the surface.
One would know by sticking two "lapped" things together. If it has a stickiness to it, then it's pretty darn flat. Wouldn't even need thermal grease at that point.
I never thought I would see a metallographic polisher on Gamers Nexus. I'm glad my super niche skillset could be used in another super niche application.
This is not how lapping a surface is done. Please do not to this, this is incorrect in every way. Where's the optical flat and monochromatic light to verify results?
Was wondering about this, also all the grinding is unidirectional, use a figure eight pattern to get even wear in all directions.
@@meareweird7714 they did mention rotating the part.
From experience, I know that the leading edge will remove more material. I sand other material than CPU's, but I alway turn the material 180 degrees to sand as flat as possible. Cool machine!
It would be nice if your "professional" camera guy could figure out how to use something besides autofocus.
Had a massive improvement on air back in the late 2000's when I finally decided to lap my q6600 and zalman cooler.
Wish I had that machine as I used a mirror and different grit sandpaper
I love the Ghost Reference... I watch you because your from my generation and it just feels right! lol
That thumbnail made my year.
